GRAIN SHOCKEB.

Application filed .Tune 9,

To @ZZ eli/720m t ymay concern:

Be it known that I, DANIEL A. YSrion- Makina, a citizen of the UnitedStates, residing at lVichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Improvements in GrainShockers; and I do declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled the artto which it appeitains to make and use the same, reference being had tothe accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates te a shocker for grain binders and harvesters,the primary object being to provide a shocker to receive vbundles ofgrain, form them into shocks and deposit them upon the ground with theheads upstanding.

The novel mechanism by which the desired result is accomplished will beappa-rent by reference to the following description in connection withthe accompanying drawings, in which Fig. 1 is a perspective view of ashocker constructed in accordance with my invention.

TEig. 2 is a plan view of the same.

Fig. 3 is a detailed perspective view of two parts of an intermittentclutch for setting the shocker into shock releasing` operation.

Fig. 8 is a detailed perspective view of the clutch controlling stop andrelease, and n Fig. 9 is a fragmentary perspective view of one end ofthe crank shaft for operating the pitmen for swinging the ,bundlereceiving members. v

The shocker frame isshown as consisting of two end frame members 1 andV2. Each end frame` member has a top rail Sand a bottom rail et, the toprail and bottom rail being connected at their ends by upriglits 5 and 6and they are braced intermediate 1924. Serial No. 718,827.

their ends by vertical braces 7. In actual' 55 practice, the top rail 3,the bottom rail 4 and the vertical braces 5 and (Scan all be made of asingle piece of strap iron.

The two frame members 1 and 2 are fastened together by cross bars 8 and9, the 60 the end 11 being fastened to the binder 12 55 'by a fasteningdevice 13.- The extended end 11 of the bar 8 has secured to it, one endof a brace 14 which is really the extended end ofthe bar Q'to assist inmaking the frame rigid.

The sprocket 15 receiving motion from the binder mechanism drives achain 16 which passes around a sprocket 17 on shaft 18 in bearing 19carried: by the bracket 2O of the shocker frame. 21 which meshes with agear 22 on the shaft 28 mounted in bearings 24C and 25 carried by theshocker frame. On the end of the shaft 23 is a clutch member consistingof a star wheel 26 keyedy to shaft and having 80 internal teeth 27adapted to Contact with the roller 28 on the projection 29 of the clutchdog 30. The clutch dog 30 is pivoted to a clutch disk 81 at 32 and thelroller 28 on projection 29 is urged into the recess be- 85 tween theteeth 27 by a tension spring 33, one end of which is connected to thedog and the other to the disk. l

The dog has a foot 34 which projects beand it may have pivotal movementbecause 1t 1s offset 1n the recess 35 1n the clutch disk The clutch diskcarries a beveled gear 3G land with the gear is loose on the shaft 23,

therefore the gear 3G will be rotated only when'the roller 28 is movedinto a recess between the teeth 27 which can be accomplished only whenthe foot 34- is free to n'icve.

Normally the dog is held out of therecess by the stop and releasedevice, best shown in Figs. 4 and 8. rfthe stop and release deviceconsists of a sleeve 87 pivoted on a spindle 38 on the frame and it hasa stop arm 39 normally iu the path of the foot Bet. It also is .ircvidedwith al crank stopVA arm 40, the purpose of which will be describedhereniafter.

The shaft 18 drives a gear 75 CII Cil

to the bo.'Y

rllhere is an arm 41 on the sleeve BT to which is connected a pullv rod42 conveniently accessible 'for en@agementl by an operator on theharvester ano` binder so that at intervals the pull rod can be actuatedto move the stop 39 out ot engagement with the toot 4. `When this isdone the spring; 3S, will'` throw the roller projection 28 into thespace between the teeth 27 and. since the clutchmember 26 is constantlyrotating' with the it will be apparentV that 'rhemcmbers 2G and 31 willbe clutched toI` `her during one complete revolution otl the shaft 23,at which 'time certain*operations will tatie place as will be apznarentatte-r the cimstruction of thev invention is betten understood. The pullrod 42 may be coi'iveniont; y att-achedto the 'bimdlecarrierfoot leveron the harvester and binder.

Mounted in bearings-@rand 44 on the top 1ails ofthe two end ktramemembers 1, and 2y is a crank shaitt 45. rllhe crank shai't is providedwith two, arms 4G and 47 owhich pitmen 48 and 49 are connected and:integral with the arms 46 and 4T are otiset cranl arms 50 and 51connected by the cross rod 52 to strengthen or brace theends of the arms50 and 51.

When the crank arms 50 and 51 are at greater radial distances from thel'iearings and 44 than the arms 4b" and 47 the throw ot tie cranks 5()andy 51 will be greater than the throw ot the cranks 46' and 4T. Conserquently the pitmen 53 andv 54. will have Lgreater amplitudes otmovementthan will lthe pitmen 48 and 49. rlhe purpose of this will be understoodby referring to Figs. 1', 2 and 7 `from which it will bel seen that theshock forming and supporting` members comprise loops 55 and 56, each of'which has a `journal 57, one mounted in lthe bearing box 58 and theother in a boi; 59.

The loops are supported at their lower ends by brackets 6() and61which:arepivoted is as indicated at 62 1) ,that is the up ,1' ond oteach bracket 50' and-61 is pivoted to its boi; so that it can swing.@nly one pivotal' connection is shown in 1 but it is to be understoodthat the bracket 51 is pivote-d to the boi; 59` in identically the sameanne? that bracket is pivoted to box 58. v

i Each loop 55 and 56 carries lateral shock supporting fingers 63, the'ers' of. one loopprojecting toward the ot er and each loop carries inladdition, aspri g-nger 6 4 to absorb the shock ,et the bundles; as theyare dropped on to theshoek receivinglingers G3. lllhe pitmen48 and 49-are .fastened to vthe outer ones of the parallel bars-65 and 68 of theloops and thefpitmen 53a1icl254pa32e fastened-tothe inner-ones ot theparallel-bars and 66. hat is the pinnen-.48 and49-are fastenedrespectfully to the ar 65 ortA the loops 55 and 56 and the pitmen 53 and54 "G3 wia..allowitbef bhtt endset .the shocls are fastened to therespective bars G6 ot the loops 55` and 56. Consequently as the shaft45' is rotated through the' gears 86 and 67 (the latter being on theshaft 45 and meshing with gear 376m),k the loops or linger supportingVmembers 55 and 56 will swing rearwardly due to the action of the pitmen48 and 49, at the same time the pitmen 53 and 54. having agheater throwof an'iplitude ot movement than the pitmen 48 and 49 will swing theloops; about the axes of the pivots 59- to cause the lingers to spreadiapart as the shatt forming members move rearwai-diy, so it will be seenthat the shaft 'forming members have twodiiterent movements imparted tothem at the sameV time', one adownwardly and rearwardly swingingmovement and the other a pivotal movement to cause the lingers 63tospread apart. This is for the purpose of releasing the shock and thispeculiar movement is due to the' fact that the stop 40- normally restsunder the crank arm 46 but when a` pull 1s nnparted to the pull rod 42to move the stop 39 out of engagement withl the toot 34, the

stop 40 is moved outl of? engagement with the crank 45 soI that atv thesame time that the clutch is permitted togo intoy ecct, the crank shaft45 which hasbeenpreviously held up by the supporting stopv or arm 40 isreleased?. Thel bundles of; grain are te@ into the oradlevor shockforming device with the heads toward, the rear and theV butts rest uponthe curved detlector plate 67 on rod 68 carried by the upper bar vlotthe end members landt 2. The butt supporting an rip-ending plate 67carries divergring angles 69 and 70 to tend to spread the butt ends ofthi` shocks, ask they move to the ground, the shocks nearl theheads oithe grain being compressed slightly by the un, wardly and downwardly andthen inwardly curved spring fingers 71 and 72 carried by the upper-bars3 of the ends 1 and 2 ot the trame. "lthe lingers 71 and 72 are a partot' the shock forming mechanism.

In actual practice l prete-r to arrange the lower ends ot the loops 55and 56 s o that they will. swing about eight inches from the ground andabout the same distance from the. guidesor angles (59A and ZO to allowroom for spreading; the butts of the shock. -The lower ends ot theshoclrl will ment when open-ine?7 thenv tast movement to fell, 'openposlton.v and'` then: a; relatively slow. final' closing movement sothat, ting o0 Contact Wit-l1 the ground and than move out of the Way ofthe shock ata rapid rate, this being necessary to prevent the shocksfrom being knocked down after they are set up as the machine travelsover the ground.

Assuming that the shocker is moving from left to righty the bundles willbe fed into the shocker Awith the heads to the rear, butts resting uponthe butt npr-end plate G7. When a 'sufficient number of bundles havebeen received in the shocker to make the shock, the operator` will pullon the pull rod 42 to rock the sleeve 37 so that the stop 39 will moveout of line with the foot 3f. The spring 33 will then be effected indrawing the dog 8O into contact with one of the teeth 27 and since the`clutch member` 26 is constantly rotating, .it will be apparent that theclutch member 26 will cause the clutch member or disk 3l carrying thedog` 30 to rotate, imparting motion to the rock shaft 45 as previousydescribed so as to dump the shock with the butt ends spread apart andthe heads rlp-ended and inasmuch as the downward swing of the cradlearms or fingers 63 will allow the butt ends to pass to the ground whilethe cradle arms or fingers 63 are spreading apart, it will be seenthatthe vertical shock must result.

The arms will support the shock long enough to cause it to tilt to avertical position and then the pitmen 53 and 54: will move the armsapart quick enough to allow the shock forming mechanism to get krout ofthe way of the shock as the machine moves forward, otherwise the shockwill be knocked down.

From the foregoing, it will be seen that a shocker may be provided whichwill proplil erly form the bundles as they come from the harvester andbinder into a shock and deposit it on the ground in an upright position.

The spring fingers not only absorb the impact of the bundles but theyalso tend to tuck in the heads of the bundles as the shock is beingmade.
